Description

Technical Field

The application relates to the field of communication, in particular to a vehicle communication method and device based on V2X.

Background

The V2X technology is a communication technology for data transmission based on a physical layer and a data link layer, and a data packet is encapsulated in a Media Access Control (MAC) frame format. Therefore, the vehicle needs to communicate with the external device by using the data packet of the vehicle through the V2X technology. However, if the vehicle (for example, the vehicle a) always communicates with the external device (for example, the vehicle B) using the data packet of the vehicle a, the vehicle B may obtain the data packet of the vehicle a multiple times, and analyze the data packet of the vehicle a, so as to obtain the related information of the vehicle a, which may cause the privacy of the user to be leaked.

Furthermore, the terms "including" and "having," and any variations thereof, as referred to in the description of the present application, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or modules is not limited to the listed steps or modules but may alternatively include other steps or modules not listed or inherent to such process, method, article, or apparatus.

In addition, in the embodiments of the present application, words such as "exemplary" or "for example" are used to mean serving as examples, illustrations or explanations. Any embodiment or design described herein as "exemplary" or "e.g.," is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "e.g.," is intended to present concepts in a concrete fashion.

In order to facilitate understanding of the technical solutions of the present application, before describing in detail the vehicle communication method based on V2X of the embodiment of the present application, a description is given of the communication system of the embodiment of the present application.

Fig. 1 is a schematic structural diagram of a communication system according to an embodiment of the present application. The communication system may include a plurality of vehicles (e.g., vehicle 1, vehicle 2, vehicle 3 … … shown in fig. 1).

Each vehicle can establish a direct connection communication link with surrounding vehicles to realize direct connection communication, such as: direct communication between the vehicle 1 and the vehicle 2 is possible. For example, a direct communication link established between a vehicle and a vehicle may be defined as a sidelink or a Sidelink (SL), and an interface for the vehicle to communicate directly with the surrounding vehicles may be referred to as a PC5 port.

In addition, the V2X communication system shown in fig. 1 may also include a radio access network device. The radio access network equipment includes a Road Side Unit (RSU). The vehicle can send the V2X message to other vehicles in a mode of transferring through the wireless access network device, and can also access the network through the wireless access network device. For example: vehicle 1 may send a V2X message to the wireless access network device, which sends a V2X message to vehicle 2. Illustratively, the interface between the vehicle and the radio access network device may be referred to as the Uu interface.

It should be noted that the V2X communication system shown in fig. 1 is an exemplary configuration diagram, and is not limited to the V2X communication system. In practical applications, the V2X communication system shown in fig. 1 may include other devices besides the devices shown in fig. 1, such as: an application server (application server), a core network device, and the like.

The vehicle in fig. 1 is not limited to any type of vehicle such as an automobile, a bicycle, an electric vehicle, an airplane, a ship, a train, a high-speed rail, and the like. The vehicle may include an in-vehicle device capable of direct communication with other devices, which may be referred to as a User Equipment (UE) or a terminal (terminal). The vehicle may be connected to another vehicle in the V2X communication system in a one-to-one manner, i.e., unicast communication, or may perform multicast communication with another plurality of vehicles in the V2X communication system. For example, as shown in fig. 2a, vehicle 1 may have a one-to-one connection with vehicle 2 for unicast communication; as shown in fig. 2b, the vehicle 1 may form a communication group with three other vehicles (vehicle 2, vehicle 3, and vehicle 4), and the vehicles in the communication group perform multicast communication. The embodiment of the present application does not limit this.

For example, each vehicle shown in FIG. 1 may include the protocol layer entities shown in FIG. 3: an application layer entity, a non-access stratum (NAS) layer entity, a Radio Resource Control (RRC) layer entity, a Packet Data Convergence Protocol (PDCP) layer entity, a Radio Link Control (RLC) layer entity, an MAC layer entity, and a PHY layer entity, and may further include a Service Discovery Application Profile (SDAP) layer entity, a V2X layer entity, or other newly added protocol layer entities (not shown in fig. 3).

The vehicle may process the transmitted data through the protocol layer entities shown in fig. 3. For example, when the vehicle 1 transmits data to the vehicle 2, the MAC layer entity of the vehicle 1 determines a first sidelink logical channel (SL LCH) and multiplexes data of the first SL LCH into a MAC Protocol Data Unit (PDU); in the case where the remaining resources of the MAC PDU are greater than zero, the vehicle 1 determines a second SL LCH different from the first SL Logical Channel Priority (LCP) according to the communication range of the first SL LCH, and multiplexes the data of the second SL LCH into the MAC PDU. Subsequently, the MAC layer entity of the vehicle 1 hands over the MAC PDU to the physical layer entity (PHY layer entity) of the vehicle 1. The PHY layer entity of vehicle 1 transmits the MAC PDU to vehicle 2 through port PC 5.

Alternatively, the device shown in fig. 1, the interface names between the respective devices, and the naming of the respective protocol layer entities shown in fig. 3 are just one example. In a specific implementation, the names of the devices, the interfaces between the devices, and the protocol layer entity may also be other names, which is not specifically limited in this embodiment of the present application.

Fig. 4 is a schematic composition diagram of a communication device provided in an embodiment of the present application, where the communication device may be used to implement a V2X-based vehicle communication method provided in an embodiment of the present application.

As shown in fig. 4, the communication device includes a processor 41 and, optionally, a memory 42 connected to the processor 41 via a communication bus 44.

As an example, the communication device may further comprise other processors, such as the processor 45 shown in fig. 4, and the processor 45 comprises an ASIC 0. Each of the plurality of processors in the communication apparatus may be a single-Core Processor (CPU) or a multi-Core Processor (CPU). A processor herein may refer to one or more devices, circuits, and/or processing cores for processing data (e.g., computer program instructions).

In the embodiment of the present application, the memory 42 may be a read-only memory (ROM) or other types of static storage devices that can store static information and instructions, a Random Access Memory (RAM) or other types of dynamic storage devices that can store information and instructions, an electrically erasable programmable read-only memory (EEPROM), a magnetic disk storage medium or other magnetic storage devices, or any other medium that can be used to carry or store desired program code in the form of instructions or data structures and that can be accessed by a computer, but is not limited thereto.

In a possible implementation, the memory 42 may exist separately from the processor 41, i.e. the memory 42 may be a memory external to the processor 41, in which case the memory 42 may be connected to the processor 41 via a communication bus 44 for storing instructions or program code. The V2X-based vehicle communication method provided by the embodiments described below of the present application can be implemented by processor 41 calling and executing instructions or program code stored in memory 42.

In another possible implementation, the memory 42 may also be integrated with the processor 41, that is, the memory 42 may be an internal memory of the processor 41, for example, the memory 42 is a cache, and may be used for temporarily storing some data and/or instruction information, and the like.

Optionally, the communication device further comprises a communication interface 43.

The communication interface 43 is used for communicating with other devices or communication networks using any transceiver or the like, such as ethernet, Radio Access Network (RAN), Wireless Local Area Network (WLAN), and the like.

The following specifically explains the vehicle communication method based on V2X according to the embodiment of the present application with reference to fig. 1 to 4. Optionally, names of the messages or names of the parameters in the messages in the following embodiments of the present application are only examples, and other names may also be used in specific implementations, and this is not specifically limited in the embodiments of the present application.

Fig. 5 is a flowchart of a vehicle communication method based on V2X according to an embodiment of the present application. As shown in fig. 4, the communication method may include:

s101, the RSU determines the physical MAC address of the RSU.

Wherein, the physical MAC address of the RSU consists of the number of the geographical area to which the RSU belongs and the number of the RSU.

According to the number of the geographical area to which the RSU belongs, the number of the RSU and a preset rule, the RSU determines the physical MAC address of the RSU.

It should be noted that the two adjacent geographic areas are numbered differently. In a geographic area, the serial numbers of all RSUs are different, and the physical MAC addresses of all RSUs are different.

In the embodiment of the present application, the preset rule is set by a developer. The preset rule is used for indicating six bytes of a physical MAC address of the RSU, wherein X bytes consist of a part of numbers in the number of the geographic region to which the RSU belongs, and Y bytes consist of a part of numbers in the number of the RSU.

For example, the number of the geographic region to which the RSU1 belongs is 110000, the number of the RSU1 is 01, and the physical MAC address of the RSU1 may be 11:00:00:00:00: 01. Wherein, the first five bytes of the physical MAC address of the RSU1 are composed of the number of the geographical region to which the RSU1 belongs, and the last byte of the physical MAC address of the RSU1 is composed of the number of the RSU 1.

It should be noted that, in order to ensure that the physical MAC addresses of each RSU in the same geographic area are different, the following two ways may be adopted in the embodiment of the present application.

In the first mode, the RSUs in the same geographical area synchronize the physical MAC address of each RSU, and the RSUs detect whether the determined physical MAC address is the same as the physical MAC addresses of other RSUs. And if the physical MAC address determined by the RSU detection is the same as the physical MAC addresses of other RSUs, the RSU determines the physical MAC address again.

In the second mode, the RSUs in the same geographical area send their respective physical MAC addresses to a server managing the RSUs, and the server detects whether RSUs with the same physical MAC address exist. And if the RSU with the same physical MAC address exists, the server sends a reconfiguration message to the RSU with the same physical MAC address, so that the RSU determines the physical MAC address again.

Optionally, the RSU sends the physical MAC address of the RSU and a preset address configuration mode to the vehicle-mounted terminal.

And S102, the vehicle-mounted terminal receives the physical MAC address of the RSU and the preset address configuration mode, wherein the physical MAC address is sent by the RSU.

The preset address configuration mode is used for indicating the vehicle-mounted terminal to generate a virtual MAC address of the vehicle-mounted terminal. The preset address configuration mode comprises the following steps: a reverse order, a Hash function (Hash function) algorithm, and the like, which are not limited in the embodiments of the present application.

In one possible implementation manner, the vehicle-mounted terminal receives a physical MAC address and a preset address configuration manner of an RSU broadcasted by the RSU (broadcast).

Specifically, the RSU may send the physical MAC address of the RSU and a preset address configuration mode to the vehicle-mounted terminal at the same time; or the RSU may send the physical MAC address of the RSU to the vehicle-mounted terminal at a first time, and send a preset address configuration manner to the vehicle-mounted terminal at a second time, where the first time is different from the second time.

In another possible implementation manner, the vehicle-mounted terminal receives an address configuration message broadcasted by the RSU, where the address configuration message is used to instruct generation of a virtual MAC address of the vehicle-mounted terminal, and the address configuration message includes at least one of a physical MAC address of the RSU and a preset address configuration manner.

Specifically, the RSU may broadcast an address configuration message once, where the address configuration message includes a physical MAC address of the RSU and a preset address configuration mode; or, the RSU may broadcast an address configuration message once at the third time, where the address configuration message includes a physical MAC address of the RSU, and broadcast an address configuration message once at the fourth time, where the address configuration message includes a preset address configuration mode. The third time is different from the fourth time.

S103, the vehicle-mounted terminal generates a virtual MAC address of the vehicle-mounted terminal according to the physical MAC address, the address configuration mode and the physical MAC address of the RSU.

According to one possible implementation mode, the vehicle-mounted terminal generates a virtual MAC address of the vehicle-mounted terminal according to the physical MAC address, the address configuration mode and the physical MAC address of the RSU. Illustratively, the physical MAC address of the RSU 12: 03: 10: 11: 11: 11, the physical MAC address of the vehicle-mounted terminal is 32: 45:35:44:18:26, and the address configuration mode is reverse order, the virtual MAC address of the vehicle-mounted terminal may be 11: 11: 11:44:18:26.

And S104, the vehicle-mounted terminal communicates with other terminals by using the virtual MAC address of the vehicle-mounted terminal.

Optionally, the vehicle-mounted terminal sends an address translation message to the RSU, where the address translation message includes: the physical MAC address of the vehicle-mounted terminal and the virtual MAC address of the vehicle-mounted terminal. The RSU establishes a physical MAC address of the vehicle-mounted terminal and a virtual MAC address of the vehicle-mounted terminal.

In the embodiment of the application, when receiving the address conversion message sent by the vehicle-mounted terminal, the RSU determines the time when the address conversion message is received. And each time the vehicle-mounted terminal arrives at the area of one RSU, the vehicle-mounted terminal sends an address conversion message to the RSU, and each RSU also determines the time when the address conversion message is received. After that, each RSU transmits its physical MAC address, the physical MAC address of the in-vehicle terminal, and the time when it receives the address conversion message to the server that manages the RSU. In this way, the server can determine the action track of the vehicle according to the physical MAC address of the RSU and the time when the RSU receives the address conversion message, and the management of the road operation unit on the vehicle is facilitated.

Illustratively, the RSU1 is in region a, the RSU2 is in region B, and the RSU3 is in region C. The time when the RSU1 receives the address translation message is 08:00, the time when the RSU2 receives the address translation message is 08:10, and the time when the RSU3 receives the address translation message is 08: 20. From this, the trajectory of the vehicle is region a-region B-region C.
